Pull Request Overview
This PR extends canonical path resolution to include Rust built-in types (e.g., str) by modeling them in the core crate and updates related tests.
- Extend
PathResolution.qllto recognize builtins undercore - Update test queries to import
PathResolutionandBuiltinsand cover atrimexample - Adjust expected outputs to include the generated
<core::str>::trimpath

The module name Bultins appears misspelled; it should likely be Builtins to match the framework's naming.

[nitpick] Consider adding parentheses around the this.getName() = "core" and child instanceof Builtins::BuiltinType clause to make grouping explicit and improve readability.

| (this.getName() = "core" and | |

For builtins, like
str, we model them as belonging to thecorecrate when computing canonical paths.
